A researcher carries out a study of memory strategies. She has all participants receive all three strategy conditions. First they get strategy A, then they get strategy B, and then they receive strategy C. She notices that there is a steady increase in performance as the students move from A to C. She is concerned because although it might be that strategy C is better than strategy A, it is also possible that the participants might just improve because of familiarity with the task of memorizing lists. Her concern reflects the potential of:

a. Order effects
b. Random assignment
c. Carryover effects
d. Random sequencing effect

Field and Lawson (2003) reported the effects of giving children aged 7–9 years positive, negative or no information about novel animals (Australian marsupials). This variable was called ‘Infotype’. The gender of the child was also examined. The outcome was the time taken for the children to put their hand in a box in which they believed either the positive, negative, or no information animal was housed (positive values = longer than average approach times, negative values = shorter than average approach times). Based on the output below, what could you conclude?

A. Approach times were significantly different for the boxes containing the different animals, and the pattern of results was affected by gender. B. Approach times were not significantly different for the boxes containing the different animals, but the pattern of results was affected by gender. C. Approach times were not significantly different for the boxes containing the different animals, but the pattern of results was unaffected by gender. D. Approach times were significantly different for the boxes containing the different animals, but the pattern of results was unaffected by gender.
